摘要
通过测定混合物吸收光谱的变化研究了两只偶氮型酸性染料C.I.酸性红337和C.I.酸性红266与阳离子表面活性剂十六烷基三甲基溴化铵的相互作用。表面活性剂浓度在CMC以下时,只有静电作用生成对离子,对离子的λmax与染料水溶液的λmax几乎相同;当表面活性剂浓度达到CMC及以上时,混合溶液的λmax增加20nm。
The interactions of two acid dyes with cationic surfactants were studied and spectrophotometry was used to study the complex equilibria between dye and surfactant in solution.
